I don't think there is an actual list website anywhere. I know the midwest collegiate dancers have a fb group that we keep updated with all our competitions (and it does stretch outside of the proper midwest too) I can list off the midwest schools, but I'm not sure about the EC.

This calendar seems relatively comprehensive (It's Ily's, right? I'm pretty sure I found it through a link here on DF at some point): http://www.dance.zsconcepts.com/comp_list.cgi . Though it looks like there are plenty of 2013 comps still needing to decide/communicate their dates.

It's nice to see some schools can have their 2013 dates already listed. But many college teams are secondary users of the available space. My college team has to wait until the athletic teams have set their home game schedules before the facility will commit to a date for our competition.
